Twelve Big 12 defensive football players have been named to the preseason watch list for the 2013 Bronko Nagurski Trophy while 10 interior lineman have been listed on the 2013 Outland Trophy Preseason Watch List.

The Bronko Nagurski Trophy is given annually to the most outstanding defensive player in college football. The award, now in its 21st season, is named after John Outland, one of the few collegiate football players to earn All-America status at two different positions. This year’s Big 12 candidates are Bryce Hager (Baylor), Ty Zimmerman (K-State), Aaron Colvin (Oklahoma), Calvin Barnett (Oklahoma State), Justin Gilbert (Oklahoma State), Shaun Lewis (Oklahoma State), Devonte Fields (TCU), Jason Verrett (TCU), Quandre Diggs (Texas), Jordan Hicks (Texas), Jackson Jeffcoat (Texas) and Kerry Hyder (Texas Tech).

This year’s Nagurski Trophy will be presented by the Charlotte Touchdown Club and the Football Writers Association of America on Dec. 3 in Charlotte, N.C.

Dating back to 1946, The Outland Trophy is awarded each season to the nation’s top interior lineman by the Football Writers Association of America.
